Impacts of agricultural research on poverty: findings of an integrated economic and social analysis por Meinzen-Dick, Ruth S., Adato, Michelle, Haddad, Lawrence J., Hazell, Peter B. R.

“…This has been the case particularly in Asia and Latin America, where the vast majority of the developing world population and the world’s poor live.3 However, the paths of causality are complex and highly contingent. The benefits do not necessarily materialize for poor people, and some effects can be negative.…”

Recent food prices movements: A time series analysis por Cooke, Bryce, Robles, Miguel

“…The empirical work presented here includes first difference models and rolling Granger causality tests. Overall, our empirical analysis mainly provides evidence that financial activity in futures markets and proxies for speculation can help explain the observed change in food prices; any other explanation is not well supported by our time series analysis.…”

Model for collaborative planning of community-managed resources based on qualitative soft systems approach por Purnomo, H., Mendoza, G.A., Prabhu, Ravi

“…Collaborative or participative modelling follows where the multiple views, perspectives and concerns are systematically organized and structured into a qualitative model describing the interrelationships, interactions, and causality relationships of the different management components, particularly the relevant indicators. …”

Environmental impacts of trypanosomiasis control through land-use change: Conceptual model, approach and preliminary results por Reid, Robin S., Kruska, Russell L., Ellis, J.E., Wilson, C.J., Perry, Brian D.

“…Geographical information systems (GIS) are used to generate hypotheses and to analyse broad-scale patterns, while field studies are used to establish causality and to ground-truth large-scale data sets. …”

A spatial analysis of land use and cover change and agricultural performance: Evidence from northern Ghana por Haile, Beliyou, Signorelli, Sara, Azzarri, Carlo, Guo, Zhe

“…Although our data do not allow us to establish causality, the evidence suggests the importance of past land-cover conditions in affecting current agricultural performance, especially in resource-stricken settings where conservation and restoration practices are not as common.…”

Monitoring and evaluation to strengthen the performance of agricultural R&D por Elliott, Howard, Lynam, John K.

“…This chapter begins with a discussion of the performance monitoring challenge in African agricultural research with respect to monitoring change in smallholder agricultural systems, the time lag in agricultural research, the context for technology adoption, and causality in agricultural research impact pathways. …”

Using the microbiota to study connectivity at human–animal interfaces por Muloi, Dishon M., Caron, Alexandre, Berkley, J.A., Hassell, James M., Brito, I.L., King, K., Moodley, Arshnee, Fèvre, Eric M.

“…We discuss the methodological challenges and gaps in knowledge in analyzing microbiota composition dynamics, the functional meaning of these changes, and how to establish causality between microbiota changes and health outcomes. …”

Maize seed demand, supply and varietal age dynamics in Ethiopia por Kebede, Jeleta, Mohammed, Abdu, Jaleta, Moti

“…We further demonstrate that while there is a bidirectional causality between maize seed supply and distribution, the relationships between maize seed demand and supply, and demand and distribution are unidirectional: previous year supply and distribution cause demand for specific variety, but supply and distribution are not responding to previous demand. …”

Analyzing crop price dynamics in Nalanda, Bihar: An in-depth analysis of twenty agricultural commodities por Mohanty, Samarendu, Bairagi, Subir, Janakiraman, Deepa, Baruah, Sampriti, Kakraliya, Manish, Krupnik, Timothy J.

“…We also observed notable linkages between smaller village markets and larger markets, influenced by factors such as minimum support prices and transportation costs. Through causality tests, we identified bidirectional influences in certain markets, revealing the complex nature of price transmission dynamics. …”

Assessing the impact of CIFOR’s influence on policy and practice in the Indonesian pulp and paper sector por Raitzer, David A.

“…A semistructured interview approach is used to trace connections between the research, immediate users and actors ‘on the ground’, which enables the establishment of causality. Triangulation through document review helps validate these causal theories, and trend series statistical tests further reinforce the concurrence of identified changes with the availability of CIFOR’s findings. …”

Drivers of food insecurity amongst the Batwa in Uganda por Ainembabazi, Triphine

“…Multilinear regression analysis was done in R studio to determine the most predictor variables and bivariate correlations were done to establish causality. The findings revealed that land and rainfall were the driving factors of food production. …”

Genetic variation between ecotypic populations of Chloris roxburghiana grass detected through RAPD analysis por Mnene, W.N., Hanson, Jean, Ekaya, Wellington N., Kinyamario, J.I., Mweki, P., Lall, G., Stuth, J.W., Jamnadass, Ramni H.

“…Although there are differences for neutral genetic markers between the populations, it is difficult to relate this directly to ecotype since correlation does not imply causality. The implication for optimising future seed collection is discussed and potential areas for further studies identified.…”

Wheat seed delivery pathways and varietal turnover in eastern India por Khed, Vijayalaxmi D., Debello, Moti Jaleta, Krishna, Vijesh V.

“…Additional qualitative interviews led to the initial impression that farmers' selection of varieties often precedes their choice of seed source, challenging the prevailing assumptions about the causal direction of this relationship. To address the challenge of reverse causality between varietal selection and seed source preference, we employed an instrumental variable regression framework. …”
